Sodium Hydroxide → N-[5-(4-{5-[(8aS)-Hexahydropyrrolo[1,2-a]pyrazin-2(1H)-ylmethyl]-1,3,4-oxadiazol-2-yl}-1H-indazol-6-yl)-2-(methyloxy)-3-pyridinyl]methanesulfonamide

Reaction Steps

N-[5-[4-{5-[(8aS)-Hexahydropyrrolo[1,2-a]pyrazin-2(1H)-ylmethyl]-1,3,4-oxadiazol-2-yl}-1-(phenylsulfonyl)-1H-indazol-6-yl]-2-(methyloxy)-3-pyridinyl]methanesulfonamide (95 mg, 0.143 mmol) was dissolved in 1,4-dioxane (1 ml) and sodium hydroxide (1 ml, 0.143 mmol) was added. The mixture was stirred at room temperature for 1 h. The mixture was dried down under a stream of nitrogen and the residue partitioned between ethyl acetate (5 ml) and saturated ammonium chloride (2 ml). The organic layer was separated, dried by passing through a hydrophobic frit and the solvent removed in vacuo to give an orange oil. This was triturated with cyclohexane to give the title compound as an orange solid (26 mg).
